Grade 201 304 316 Ss Coils Cold 0.2mm-12mm Polished hot rolled Stainless Steel Coil

304 Stainless Steel Coil:

• The most commonly used austenitic stainless steel, with excellent corrosion resistance and formability.
• Widely used in food processing equipment, chemical equipment, architectural decoration, etc.

316L Stainless Steel Coil:

• Contains higher molybdenum content, offering better corrosion resistance, especially suitable for marine environments.
• Commonly used in chemical equipment, pharmaceutical equipment, marine equipment, and other applications requiring high corrosion resistance.

309S/310S Stainless Steel Coil:

• Contains higher chromium and nickel, with excellent high-temperature resistance.
• Mainly used in high-temperature equipment such as chimneys, furnace covers, and furnace linings.

430 Stainless Steel Coil:

• A chromium-based martensitic stainless steel, with lower corrosion resistance than 304, but lower cost.
• Commonly used in home appliances, kitchen equipment, architectural decoration, and other cost-sensitive applications.

410/420 Stainless Steel Coil:

• Chromium-based martensitic stainless steel, with higher hardness and strength.
• Primarily used in tools, molds, valves, and other applications requiring high hardness.

The different grades of stainless steel coils vary in chemical composition, mechanical properties, and corrosion resistance. When selecting, the choice should be based on the specific application environment and requirements,

Hot-Rolled Stainless Steel Coils:

• Manufacturing Process:

  • Stainless steel is first cast into ingots or continuous cast into slabs.
  • The slabs are then reheated and passed through a series of rolling mills at high temperatures, typically around 1100-1200°C.
  • This hot rolling process reduces the thickness and increases the length/width of the steel.

• Key Properties:

  • Thicker cross-section compared to cold-rolled coils, typically ranging from 3mm to 12mm.
  • Exhibit higher strength and hardness due to the hot working process.
  • Have a distinctive mill scale appearance on the surface.
  • Lower formability and ductility compared to cold-rolled coils.
  • Generally have lower dimensional accuracy and tighter tolerances.

• Common Grades:

  • 304, 304L, 316, 316L, 430, 409, 410 are some of the popular hot-rolled stainless steel grades.

• Applications:

  • Construction and infrastructure (e.g., bridges, buildings, facades)
  • Automotive and transportation (e.g., exhaust systems, suspension components)
  • Industrial equipment and machinery
  • Heavy-duty applications requiring high strength and durability
